9、0-2.11.2:1980 ii BSI 10-1999 Foreword This standard makes reference to the following British Standards: BS 5550-2.9.1, Dimensions of spools for16mm motion-picture projectors (up to and including120m capacity:18cm size). BS 5550-2.9.2, Spools for16mm motion-picture projectors (from244m to610m capacit
10、y:24cm to38cm size). BS 5550-2.9.3, 16mm film spools of732m capacity (43cm size) for specialized equipment. BS 5550-2.11.1, Dimensions of spindles for16mm motion-picture camera and projector spools. This British Standard has been prepared under the direction of the Cinematograph Standards Committee.
11、 It is a revision of BS4629 which provided for two grades of spindles. The first, a normal grade, was appropriate for equipment such as projectors, editors and rewinders designed for spool capacities up to and including120m. This grade is now specified in BS5550-2.11.1. The second, a precision grade
12、, the subject of this standard, is appropriate for high grade projectors and editors (which normally have a spool capacity greater than120m), laboratory processing equipment, telecine machines, and professional equipment generally. All British Standards on cinematography are eventually to become Sec
13、tions or Subsections of BS5550. Accordingly this revision is renumbered as BS5550-2.11.2. BSI Sectional List1, obtainable free from BSI Sales Department, catalogues the British Standards on cinematography. The latest edition of SL1 should be referred to particularly in view of this development. A Br
14、itish Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a fr

16、tandard relates to the dimensions of take-off and take-up precision grade spindles for16mm cinematograph equipment and telecine machines. It is related to the dimensions for film spools specified in BS5550-2.9.1, BS5550-2.9.2 and BS5550-2.9.3. 2 Dimensions Precision grade spindles shall conform to t
17、he dimensions and tolerances given inFigure 1 orFigure 2. NOTE 1BS 5550-2.9.2 and BS 5550-2.9.3 require that such spools shall have aligned square spindle holes in both flanges. For equipment which does not have to accommodate spools having the round/square combination of hole, the full length squar
18、e spindle shown inFigure 2 is recommended. Such spindles should have a domed or chamfered end to permit ease of mounting the spool. NOTE 2In certain conditions within the specified tolerances for the co-axiality of the square and round portions of the spindle, a “witness mark” may occur on the round
19、 portion.BS 5550-2.11.2:1980 2 BSI 10-1999 Figure 1 Precision grade square-round spindles for 16 mm cinematograph and telecine equipmentBS 5550-2.11.2:1980 BSI 10-1999 3 Figure 2 Precision grade square spindles for 16 mm cinematograph and telecine equipmentBS 5550-2.11.2: 1980 BSI 389 Chiswick High
